2 mac minis here one a dual core intel now both slower to boot up and desktop icons appear at least 10 secs seconds after the dock, what's the reason I wonder ?

over 200MB for the intel about 22MB for the G4 btw

A slow startup immediately following an update is normal. After that, subsequent restarts should go back to normal. If the delay doesn't get better, you should go into System Preferences> Accounts > Login Items tab and try removing the items on the list one at a time. You might be able to find the culprit there. You should also try repairing your permissions in Disk Utility.

Thanks repairing disk permissions made all the difference BUT I have lost my dual boot icons as I have XP also installed via boot camp, any way to get this back ??

Really? Who is they? I've just spent 10 min searching Google and Apple to find out and couldn't find anything catastrophic. If you could point me in the right direction...

There were a spate of post on Friday night last week when 10.4.8 released and a number of people had issues with the CS products, it seems to have died off pretty quick so it was either a rumor that got it's legs fast and lost them just as fast or it hit a very small number of people. But I do recall reading this several times last weekend._________________| Mac mini 2011 | Apple Thunderbolt Display | Apple keyboard and Magic TrackPad | 2Tb Time Capsule | Apple TV (3) | iPhone 4s |

Another CoreDuo mini here, and everything appears in good working order. I only use one MS app (Messenger, and at that, only when absolutely necessary, as I prefer Fire or Adium for their snappiness) and it appears to run fine. System was slower after the update, but I hadn't run my Onyx maintenance scripts in a couple of months, and I shut down once every couple of days.

After the scripts, we're back to like-new performance. Maybe even snappier app loads than before (only Universal apps though, Rosetta still takes a good 5 seconds to awaken a PPC app). Didn't repair permissions until afterwards either.

Do these "lots of people" on Intel Macs know the importance of letting Software Update do it's business without other apps running? I'll bet thats part of their problem. These are not Wintels.

They crash whether or not you run other apps during update. _________________~ OffaBroadway~
